What HP said.
I have two, both Sonys. One is the former flag ship machine (fantastic picture and phenomenal sound!) the other the BDP-550. I'd recommend a Sony, I've had no problems and they're wonderful machines. Here's the recent models:

I have the Star Trek set, I commented on it in the Star Trek Movie thread. It looks fantastic. I am watching the original, not the "expanded" versions. Incredibly well restored.
